## Finding and Calculating an Empirical Formula of a Compound | How to Pass Chemistry

In this video you are going to learn how to calculate a compound’s empirical formula. Alright, let’s do this! Hello hello! Melissa Maribel here and I help students like you understand what you just learned in class so you stress less and graduate faster. Hit that subscribe button and we’ll pass Chemistry together. Today’s topic […]

## Mendelian Inheritance for NEET, AIPMT, MCAT, AIIMS, JIPMER

hello everyone today’s topic is mendelian inheritance .Sir Gregor Johann Mendel is father of Genetics. He was an Austrian monk who performed his experiment in the kitchen garden of the monastery in which he lived. he started his experiments in 1856, published them in 1865 and died in 1884. His work did not receive any […]

## Converting Between Moles, Atoms, and Molecules

In this video, we’re going to learn how to convert back and forth between moles and the number of atoms or molecules we have. Now when we do conversions like this, atoms and molecules are sometimes both referred to as particles. A particle is just a word for any individual thing so a particle could […]

## Converting between Moles, Atoms, and Molecules (Part 2)

This is the second part to converting between moles, atoms, and molecules. We’re going to do some more practice problems but if you haven’t seen the first video, check that out first and then come and watch this. How many molecules in 0.63 moles of molecules? Now we’re talking about molecules here, before we were […]

## Empirical Formula vs Molecular Formula Calculations for the MCAT

Leah here from leah4sci.com and in this MCAT video we’re going to look at Empirical versus Molecular Formula. You can find this entire video series along with the reactions and stoichiometry practice quiz by visiting my website leah4sci.com/reactions. The molecular formula as the name implies gives us the formula or the equation for a specific […]

## Pedigree Analysis – Part 2: Sex-linked Inheritance Patterns

Pedigree analysis: What are the patterns of sex-linked inheritance? In the previous Chalk Talk episode, we focused on autosomal or non-sex linked inheritance patterns. They affect any trait whose genes are located on autosomes. Autosomes are the chromosomes 1 to 22 of which two copies of each are present in males and females. Sex-linked inheritance […]

## Pedigree Analysis – Part 1: Autosomal Inheritance Patterns

Pedigree analysis – What are the patterns of autosomal inheritance? What’s the probability of inheriting certain genetic disorders? Pedigree analysis is usually quite helpful in answering this question. Fortunately, a thorough understanding of human genetics isn’t required to do so. Usually, an overview of classical hereditary suffices. We’d like to provide you with this overview […]

## Beta Thalassemia; Causes and Types (minor, major and intermedia)

All right welcome back, so we have been talking about anemia, microcytic anemia, now we’re talking about Thalassemia…in the last video we have talked about alpha-thalassemia (link in description). Today. We’ll talk about beta thalassemia So, Beta Thalassemia is a microcytic anemia, and again symptoms of anemia Tired and pale, pale and tired…sometimes, I have […]

## Molecular Weight and Formula Weight in MCAT General Chemistry

Leah here from leah4sci.com and in this MCAT Chemistry video, we’re going to look at Molecular Weight or Formula Weight. Molecular weight as the name implies is the weight of a given molecule. This is slightly incorrect because weight implies mass times gravitational acceleration and that would mean the weight on earth. Keep in mind […]
