## How many molecules are contained in 7.50 moles SO2?

Explanation: So if there are 7.50 mol SO2 molecules; there are **7.5×NA individual S**O2 molecules, and in that quantity there are 7.5×NA individual S ATOMS, and 15×NA individual O atoms.

## What is the total mass of 0.75 mol of SO2?

Answer: The total mass of 0.75 moles of SO2 is **48 grams** Explanation: To find the total mass of 0.75 moles of SO2 in grams, you must first determine the molar mass of the compound.

## What is the mass of 0.5 mole of SO2?

**16 amu**. Step-by-step explanation: One mole of sulphur contains 32 amu. so 0.5 mole will have 16 amu.

## How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 ^{23}) Na atoms, or **1.2044 × 10 ^{24} Na atoms**.

## What is the total mass in grams of 0.75 mol of?

Explanation: So, if there are 0.75⋅mol , the mass is 0.75⋅mol ×**64.07⋅g⋅mol−1 ≅48⋅g** .

## What has the greatest molecular mass?

The answer choice with the largest atomic molar mass is **(b) lead**. Molar mass is defined as the mass of one mole of an element or compound.

## How many moles are in 100 grams of NO2?

Re: Mass-Mole Conversion

You need to plug atomic masses into the formula to get the formula mass. This is approx **44**. So 1 mole of N_{2}O weighs about 44g. If you have 100.0g of N_{2}O, then you have more than 1 mole and you can calculate this.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## What will be the mass of 3 moles of SO2?

Calculation of the molar mass of given chemicals

Molar mass of = 1(S) + 2(O) = 1 (32) + 2 (16) = 32+32 = **64g**.

## Is the mass of 1 mole of oxygen and 1 mole of sulphur is same?

O molecules contains 6.022 x 1023 molecules. 1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1. … One atom of sulfur has a mass of **32.07 amu**; one mole of S atoms has a mass of 32.07 g.
