The computation would be:moles = mass/ Molar Mass, but we are looking for the mass, so rearranging, will give us: mass = moles x MM 
Q = moles x Hf 
Q = (mass/MM) x Hf 
mass = (Q x MM) / Hf 
= (1.50-kJ x 18.0-g/mol) / 6.01-kJ/mol 
=4.49 g H20 is the answer

Alexandra [31]

Answer: First you must convert pound in kilogram, and feet in meter

Explanation:

To calculate momentum we use .

p=m*V

mass-m

speed-V

distance and time are used to calculate velocity(speed)

You are given :

 mass- in pounds

for distance - in feet

before you do any calculation first you have to convert pounds in kilograms

and feet in meters.
