It all depends what the substance is.
If it's 28 grams of air, the volume is large.
If it's 28 grams of rock or lead, the volume is much smaller.
get the volume of the chemical and the mass and divide the mass by it's volume
Mass density is the amount of mass (g) per unit of volume (cm3). Divide mass by volume to get density: 15.2 grams / 0.8 cm3 = 19 grams/cm3
1 cup = 226,79 grams / 226,79 grams = 1 cup
0.735294118 grams per square meter because D=Mass/volume.
The volume is 19,245 cm3.
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
Assuming the volume is in cubic cm and not cm(!), Density = Mass/Volume = 56g/28cm3 = 2 grams per cm3
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
mass is to grams
The mass of 40 grams is 40 grams and the volume of 20mL is, wait for it, ... 20 mL!
Grams is NOT a unit of volume. It is a unit of weight or mass.
Mass per volume Mass in grams volume in cubic centimeters
Mass per volume Mass in grams volume in cubic centimeters
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter
Mass per volume Mass in grams volume in cubic centimeters
Mass and volume use different units of measure. Mass uses grams as a unit of measurement; however 1000 grams equals 1 kilogram. Volume is measure by liters.
