WebAnswer (1 of 5): Basically, you need to determine the number of moles in 12.2g of zinc atoms and then convert it to the number of atoms of zinc using the Avogadro number. The Avogadro number is 6.022 x 10^23 particles in one mole. The Avogadro number is useful because 1 mole of anything contains...

WebYes; the answer has the correct units of grams of Zn. Is the number of significant figures correct? Yes; the number of significant figures is correct because there are three signifi-cant figures in the given value of 0.366 mol Zn. Is the answer reasonable? Yes; 0.366 mol is about 1/3 mol. 23.9 g is about 1/3 the molar mass of Zn. 65.39 g Zn 1 ... WebApr 1, 2024 · Zn + 2HCl = ZnCl2 + H2 from this you need to convert both masses given to moles. Zn= 26g/65.39g/mol= .40 moles Zn. HCl =42g/36.45/mol =1.16mol HCl. Looking … kensington streets of death

WebJul 29, 2024 · From the balanced equation, there is 1:1 mol ratio between zinc and hydrogen gas. So, the moles of Zn used will also be 0.00623. Multiply the moles by molar mass to convert into grams. Molar mass of Zn is 65.38 gram per mol. = 0.407 gram. So, 0.407 grams of Zn have been consumed. WebSuppose 65.38 grams of Zn are added to a concentrated hydrochloric acid solution and hydrogen gas is liberated according to the following equation.
