2 g HCl are equivalent to 0,0548 moles.
How many moles are present in 92 grams of ethyl alcohol?
The answer is 14 moles.
1+7+(8x3) =32 =32x2 (2 moles) =64
The synthesis reaction is 2 H2 + O2 = 2 H2O. Every two moles of hydrogen reacts with one mole of oxygen to make two moles of water. Then 30.0 grams of water is 1.67 moles, and 1.67 moles of H2 has a mass of 3.37 grams. 25.0 grams of O2 is .781 moles, so 1.562 moles of H2 are needed, or 3.15 grams.
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
987 grams of Ra(OH)2 is equivalent to 3,78 moles.
