The answer is 24,92 g nitrogen.
15 grams of nitrogen are equal to 1,071 moles.
35.0 moles nitrogen (1 mole N/14.01 grams) = 2.50 moles nitrogen ----------------------------
550 g of nitrogen dioxide is equal to 11,94 moles.
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
7,68 grams of calcium nitride is equal to 0,052 moles.
850,49 g of NF3 = 11,9784 moles
4.91 mol * 6.02214129(27)×1023 / mol = 2.96 ×1024
15 grams of nitrogen are equal to 1,071 moles.
2.67 g NF3 x 1 mole NF3/71 g NF3 x 3 mole F/mole NF3 = 0.113 moles Fluorine
There are 29/14, or just over 2 moles of nitrogen in 19 grams.
35.0 moles nitrogen (1 mole N/14.01 grams) = 2.50 moles nitrogen ----------------------------
10 grams NO2 (1 mole NO2/46.01 grams) = 0.217 moles nitrogen dioxide ======================
molar weight of N = 14 grams/mole 35.7 grams/14 grams/mole = 2.55 moles
550 g of nitrogen dioxide is equal to 11,94 moles.
how many moles of sulfur are present in 3.4 moles of Al2(SO4)3
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
