How many grams of magnesium nitride can be made from 55.3 grams of magnesium if all the magnesium reacts only with nitrogen?
Balanced equation first. 3Mg + N2 -> Mg3N2 55.3 grams Mg (1 mole Mg/24.31 grams)(1 mole Mg3N2/3 mole Mg)(100.95 grams/1 mole Mg3N2) = 76.5 grams Mg3N2 made ===================
How many moles Fe are in a sample of Fe2O3 that contains 100g O?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
How many atoms of oxygen are there in 698 grams of AlNo33?
Quite a few! 698 grams Al(NO3)3 (1 mole Al(NO3)3/213.01 grams)(9 moles O/1 mole Al(NO3)3)(6.022 X 1023/1 mole O) = 1.78 X 1025 atoms of oxygen ======================
How many moles are in 182.7 g Fe?
For this you need the atomic (molecular) mass of Fe2(SO4)3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Fe2(SO4)3=400.1 grams768 grams Fe2(SO4)3 / (400.1 grams) = 1.92 moles Fe2(SO4)3
Are 3 moles of gold heavier than 10 moles of iron?
Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)
How many grams 3 of HF?
60
How many grams are In 3 of HF?
60 g
How many grams of hydrogen are there in 150 g of ammonia?
150 grams NH3 (1 mole NH3/17.034 grams)(3 mole H/1 mole NH3)(1.008 grams/1 mole H)= 26.6 grams hydrogen=================17 g of ammonia has 3 g of hydrogen.So 150 g of ammonia will have 26.5 g of hydrogen
The mass of 3 moles of ammonia would be how many grams?
3 moles of ammonia is 51grams. One mole is 17 grams.

How many moles Fe are in a sample of Fe2O3 that contains 100g O?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
How many grams of calcium in 34.5 of Ca CO 3?
34.5 g CaCO3 (1 mole CaCO3/100.09 g)(1 mole Ca/1 mole CaCO3)(40.08 g/1 mole Ca) = 13.8 grams calcium ===============
How many grams of iron could be recovered from 75.89 g FeO?
75.89 grams of FeO is equal to 1.06 moles of iron II oxide. In decomposition, there would be 1.06 moles of iron recovered, or 58.99 grams.
How many atoms of oxygen are there in 698 grams of AlNo33?
Quite a few! 698 grams Al(NO3)3 (1 mole Al(NO3)3/213.01 grams)(9 moles O/1 mole Al(NO3)3)(6.022 X 1023/1 mole O) = 1.78 X 1025 atoms of oxygen ======================
How many grams of v203 would you need to have 7.56e11 atoms of oxygen?
7.56 X 1011 atoms of oxygen (1 mole O/6.022 X 1023)(1 mole V2O3/3 mole O)(149.88 grams/1 mole V2O3) = 6.27 X 10 -11 grams vanadium oxide ===========================
Will 27 grams of aluminium react completely with 24 grams of oxygen?
Yes.Explanationary:27 g Al = 1.0 mole Al24 g = 1.5 mole O2 so this ratio (in mole) is 1:1.52Al + 3O2 --> Al2O3 so the balanced mole ratio is 2:3 or 1:1.5
What is the molar mass of 3-thiapentane?
90.19 grams/mole
