WebJan 2, 2024 · Using the Law of sines, we can say that: sin112 ∘ 45 = sin B 24 0.9272 45 ≈ sin B 24 24 ∗ 0.9272 45 ≈ sinB 0.4945 ≈ sinB Then, we find sin − 1(0.4945) ≈ 29.6 ∘. Remember from Chapter 3 that there is a Quadrant II angle that has sinθ ≈ 0.4945, with a reference angle of 29.6 ∘. So, ∠B could also be ≈ 150.4 ∘. WebA chemist adds 3.00 \mathrm {~g} 3.00 g of zinc to a solution containing an excess of silver nitrate. Only 7.2 \mathrm {~g} 7.2 g of silver metal is collected by the end of the investigation.
