Answer:1:1
There is a 1:1 molar ratio between magnesium and magnesium chloride. Magnesium has a molar mass of 24.31g/mol.
Explanation:
If you begin with 25.0 g of magnesium, how many moles of magnesium oxide will ... g C9H8O4. Now calculate percent yield. % yield = actual theoretical. × 100 =.
Answer:
The answer is
<h2>877 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 19.3 g/cm³
volume = 44.9 cm³
The mass of the gold bar
mass = 19.3 × 44.9 = 866.57
We have the final answer as
<h3>877 g</h3>
