Final answer:
To obtain 15.0 g of chromium, you would need approximately 779.94 g of the meteorite.
Step-by-step explanation:
To determine how many grams of the meteorite are needed to obtain 15.0 g of chromium, we need to calculate the molar mass of chromium. The molar mass of chromium is 51.996 g/mol. We can use the following equation to calculate the mass:
Mass = moles × molar mass
Now, let's substitute the values into the equation:
Mass = 15.0 g × (51.996 g/mol)
By performing the calculation, we find that you would need approximately 779.94 g of the meteorite to obtain 15.0 g of chromium.
