Answer:

130,000 cubic centimeters

Explanation:

The volume of a box is its length multiplied by its width multiplied by its height (lwh). 423 times 12 times 25 is 126,900. When multiplying, the number of significant figures is the same as the number with the least number of significant figures. The correct number of significant figures in this example is 2, so 126,900 would need to round up to 130,000 in order to have 2 significant figures.

How many grams of magnesium metal will react completely with 6.3 liters of 4.5 M HCl? Show all of the work needed to solve this
Rufina [12.5K]
Mg (s) + 2 HCl (aq) -> MgCl2 (aq) + H2 (g)

1) Number of mols of HCl, n

n = 6.3 L * 4.5 mol/L = 28.35 mol

2) ratio: 2 mol HCl / 1 mol Mg = 28.35 mol HCl / x mol Mg

x = 28.35 mol HCL * 1 mol Mg / 2 mol HCL = 14.175 mol Mg

3) Convert mol to mass using atomic mass of Mg

14.175 mol Mg * 24.3 g Mg / mol Mg = 344. 45 g

Answer: 344.45 g
