What is the mass of 3 moles of NO2 gas?
We are given with the moles of nitrogen (N) is 3 moles. Molar mass of nitrogen is 14 amu or 14 grams. Thus 28 grams of nitrogen occupies 22.4 litres at STP and is 1 mole. Mass in grams of 3 moles of nitrogen is 3 × 14 = 42 grams .
What is the mass of 3.45 NO2?
What is the mass of 3.45 moles of NO2? Answer: The mass of nitrogen dioxide for given number of moles are 158.7 grams.
What is the total mass in grams of 0.75 mole 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 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.
How many moles are in 22 grams of co2?
(Atomic masses : C = 12 u, O = 16 u) So, the mass of 1 mole of carbon dioxide is 44 grams. Thus, 22 grams of carbon dioxide are equal to 0.5 mole.
What is the mass percent of NO2?
Nitrogen Dioxide, NO2 Relative molar mass, Mr = 14.0 +16.0 x 2 = 46.0 g/mol Percent composition oxygen = 32.0/46.0 x 100 = 69.6% Percent composition nitrogen = 14.0/46.0 x 100 (or 100 – … 2 oxygens divided by 1 NO2 –> 32/46 x 100.
How many molecules are there in 122 grams of NO2?
Answer Expert Verified
Number of molecules = 1.47 × 10^(23) molecules. Thus, there are 1.47 × 10^(23) molecules present in 122 grams of NO2.
