Question

RACTICE Uranium (molar mass = 283.03 g/mol) has the largest molar mass of any element naturally found on Earth. What is the mass of 7.50 mol of uranium?​

Answer 1

The answer is 2122.73 g

Step-by-step explanation:

The mass of a substance given it's molar mass and number of moles can be found by using the formula

mass = Molar mass × number of moles

From the question

molar mass = 283.03 g/mol

number of moles = 7.5 mol

So we have

mass = 283.03 × 7.5 = 2122.725

We have the final answer as

2122.73 g
