How many sulfur molecules are in sodium sulfide?
We refer to "molecules" of sodium sulfate as formula units. The formula is Na2SO4. The molar mass is 142 g/mole. And sulfur (S) is 32 out of the entire 142 g. So, percent sulfur is 32/142 (x100%) = 22.5%
How many moles of sodium sulfate are present in 284 g?
To find the number of moles of sodium sulfate in 284 g, you need to divide the given mass by the molar mass of sodium sulfate. The molar mass of sodium sulfate (Na2SO4) is 142 g/mol. So, 284 g / 142 g/mol = 2 moles of sodium sulfate.
What does it mean that my Hcg level was at 142 then 146?
It normally means that your Hcg level has increased.
What is the equivalent weight of sodium sulfate?
The equivalent weight of sodium sulfate is 142 g/mol. This value is calculated by taking the molar mass of sodium sulfate (142 g/mol) and dividing it by the number of equivalents of the compound (2 equivalents, as each formula unit can donate 2 moles of charge during a reaction).

How do I calculate the percent composition of the following by mass with 3 significant figures O in Na2SO4?
Add up the compound's molar mass: Na=2(23), S=1(32), O=4(16). Sum is 142. Oxygen's part of that total is 64 (16x4). Percent is part/total, so 64/142 = 0.4507 = 45.1%.
What is the Milligram equivalent weight of sodium sulfate?
The milligram equivalent weight of sodium sulfate is 142.04 mg, calculated by dividing the molecular weight of the compound (142.04 g/mol) by 1000 to convert it to milligrams.
What is the altitude of Louisville Kentucky?
Louisville lies 466 feet above sea level (142 m).
What is 85 of 142?
85% of 142= 85% * 142= 0.85 * 142= 120.7
