I have four science questions, I really don't understand science much and the math part is even harder. So could someone help me with these 4 questions?
1. How many grams are there in 2.50 moles of potassium nitrate kno3?
2. How many moles of silver nitrate are there in 80.00 grams of silver nitrate AgNO3?
3. How many moles of phosphoric acid H3PO4?
4. How many moles of magnesium chloride are there in 148 grams of magnesium chloride MgCl2?
Thank You!!

- molecular weight of Potassium Nitrate or grams The molecular formula for Potassium Nitrate is KNO3. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Potassium Nitrate, or 101.1032 grams.
- There are ~0.4709 mol AgNO3 in 80.00 g.
- The SI base unit for amount of substance is the mole. 1 grams H3PO4 is equal to 0.010204583427424 mole.
- 148 g / 95.211 g/mol = 1.55444 m Rounded to three significant figures, the answer is 1.55. mol
