## How many moles are in 4 grams of methane?

›› More information from the unit converter

How many grams Methane in 1 mol? The answer is **16.04246**. We assume you are converting between grams Methane and mole. You can view more details on each measurement unit: molecular weight of Methane or mol The molecular formula for Methane is CH4.

## Which contains the largest number of atoms?

**4 g of hydrogen contains the largest number of atoms.**

- (A) 4 g of hydrogen (molar mass 2) corresponds to 2 moles of molecules or 4N number of atoms where N is the Avogadro’s number (6. …
- (B) 16 g of oxygen (molar mass 32) corresponds to 0.5 moles of molecules or N number of atoms where N is the Avogadro’s number (6.

## How many atoms are in h202?

**Two hydrogen atoms** can also bond with two oxygen (O) atoms (peroxide), making the formula H2O2. There is only one more oxygen atom than water (H2O) but it is a totally different compound. You can see that each of the oxygen atoms has eight electrons and the two hydrogens have two electrons each.

## How many atoms are in 16g methane?

Mass of one mole of substance is called molar mass. Or molar mass of an element is equal to the molecular weight. Therefore there are $3.01 times {10^{23}}$ **atoms** in $1.6{{g}}$ of **methane**. Hence the correct option is C.

## How many hydrogen atoms are in 16 grams of methane?

According to its chemical formula, it has one carbon atom and **four hydrogen atoms**.

## How many hydrogen atom are there in 30 gram of methane?

We work out the molar quantity of methane….. Moles of methane=25.3⋅g16.04⋅g⋅mol−1=1.584⋅mol . And since there are **4 mole of hydrogen** ATOMS per mole of methane……we gots……

## How much hydrogen in moles are there in a gram of methane?

Every mole of methane contains **2 moles** of H2 ( 4H ).

## How many atoms are in 2 moles of methane?

We’re asked to determine the number of hydrogen atoms contained in 2 moles of methane (CH_{4}). The answer is option d): there are **4.82×10 ^{24} atoms of H methane**.

## How many moles are in 25 grams of ammonia?

Answer and Explanation: let us first calculate the molar mass of ammonia gas. This means 17 g of ammonia gas is equivalent to 1 mole of ammonia gas molecule. Hence, there are **8.856×1023 8.856 × 10 23 molecules** in 25 g of ammonia.
