To find the density of any sample, you need to know the Mass (grams), and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get a sample's Density.
Density (P)= Mass(m)/Volume(V)
P=m/V
P=245.8grams/94ml
<span>P=2.65grams per ml </span>
Answer:
Workplace Hazardous Materials Information System
WHMIS is a short form for Workplace Hazardous Materials Information System. It is a comprehensive plan for providing information on the safe use of hazardous materials used in Canadian workplaces. Information is provided by means of product labels, material safety data sheets (MSDS) and worker education programs.
The water cycle regardless if it is in a lake, our bodies, food, or underground.
Number of moles of CO2 =
Mass /Ar
= 50.2 / (12 + 32)
1.14 mols
For every 1 mol of gas, there will be
24000 cm^3 of gas
Vol. = 1.14 x 24 dm^3
= 27.36 dm^3
4.00 moles of sodium has a mass of 91.96 grams.
To find an element's molar mass, you can use its atomic weight.
