Name two bases that react with dilute sulphuric acid to give zinc sulphate?

N= 3.2 moles, t = 50 + 273 = 323 k, p = 101.325 kpa, r = 8.314 l.kpa/k.mol pv = nrtv = nrt / p substituting.v = (3.2 mole)(8.314 l.kpa/k.mol )(323 k) / (101.325 kpa)hope this

The rules are different for multiplication and addition, but the least precise value always restricts the answer. first do the multiplication (as per standard order of operations): 24.6681 × 2.38 ≈ 58.7 since 2.38 has the fewest significant figures, it is considered the lease precise value then do the addition: 58.7 + 332.58 ≈ 391.3 since 58.7 has fewest figures right of decimal it is considered least precise. so final answer: 391.3 with four significant figures.
