There is no element or common compound with a density of 45kg/m3 = 1.047 kg/m3. But it could be a mixture of two or more substances: at least one of which has a higher density and at least one has a lower density.
Density = about 116.28 g/cm3
Density = Mass/Volume =3.21/45 =7.13g/cc Spec Grav = density of substance/ density of water =7.13/1 =7.13
Density = Mass / Volume Density = 45grams/5ml = 9g/ml
Density = mass / volume. If you mean 4 _cubic_ centimetres, the density is 11.3 grams per cubic centimetre. This is the density of lead.
density = mass/volume mass = 245-200= 45 grams volume 26 mL = 45g/26ml =1.7 g/ml
Density = about 116.28 g/cm3
density = mass/volume = 45kg/43m3 = 1.05 kg/m3 (rounded)
Density = Mass/Volume =3.21/45 =7.13g/cc Spec Grav = density of substance/ density of water =7.13/1 =7.13
You can use the density of the object. Density is the mass per unit volume of a substance. Density = mass / volume. Rearrange it to solve for mass. Mass = density x volume. You can find the density of the substance from a table of densities. Or depending on what you know about the substance:- moles = volume (dm3) x concentration (moldm-3) moles = mass/Mr Mr = molecular weight 100cm3 = 0.1dm3 If you know the volume, concentration and the Mr then mass can be solved by calculating the moles of the substance and multiplying by Mr.
The gram is unit of mass and the litre is a unit of volume.You can dissolve 45 g in what volume you want.
Density = Mass / Volume Density = 45grams/5ml = 9g/ml
You have a rock with a volume of 15 cm3 and a mass of 45 g. Find more answers
To find density, you must use the formula of D=M/V or density = mass divided by volume. You have given us 9g as a volume, but that should be either liters or some other measurement of volume. I'll assume liters. 45/9 = 5. So, The density of a solid that has a mass of 45 grams and a volume of 9.0 liters would be 5 grams/liter.
45/15= 3 Where density is equal to mass over volume
45 + 43 = 88
Density = mass / volume. If you mean 4 _cubic_ centimetres, the density is 11.3 grams per cubic centimetre. This is the density of lead.
The atomic number is 21: The mass number is the sum of protons and neutrons, while the atomic number is the number of protons, designated n. From the statement of the problem, n+n+3 = 45, or 2n = 42, or n=21.
