Answer:
Molar mass and Mass
Explanation:
The relationship between mass and number of moles is given as;
Number of moles = Mass / Molar mass
Mass = 1.6 g
Molar mass of HCl = ( 1 + 35.5 ) = 36.5 g/mol
Number of moles = 1.6 g / 36.5 g/mol
Number of moles = 0.0438 mol
Answer:
Explanation:
Look up the density of the material the object is made of in kg/m³.
Measure the volume of the object in m³.
Multiply the density by the volume.
You will then have the mass of the object in kg.
