Show the numerical setup for calculating the number of moles of SnO^2 in the 3.00 gram sample

Explanation:

Base your answer to the question on the information below and on your knowledge of chemistry. At 1023 K and 1 atm, a 3.00-gram sample of SnO2(s) (gram formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below. SnO2(s) + 2H2(g) → Sn(L) + 2H2O(g) Show a numerical setup for calculating the number of moles of SnO2(s) in the 3.00-gram sample.

answer; i believe the correct answer is (solid gold);
