Definitely B. Chemicals are used to help clean difficulties items/objects
Answer:
27.03 grams
Explanation:
moles (n) = mass(m)/Molar mass(M)
moles = 1.59
mass = ?
N = 14, H = 1
M(NH3) = 14 + 3(1) = 17
Substitute the values into the equation:
nM = m
∴ m = 1.59 × 17 = 27.03
CuSO₄+ Zn = Cu + ZnSO₄
1 mole Zn ---------> 1 mole Cu
3.8 mole Zn ------> ?
moles Cu = 3.8 x 1 / 1
= 3.8 moles of Cu
