I would guess 250 grams.
Using those exact quantities, we can calculate that the mass is precisely 10 grams.
Density = Mass/Volume. You cannot calculate density without knowing BOTH mass and volume.
density=mass/volume volume=mass/density
You don't, because they're different types of units. Microns measure length and grams measure mass.
Density is defined as mass per unit volume. In this particular question, the information on volume is not given. Whereas three linear measures are required to calculate a volume, only one is given. It is therefore not possible to determine the volume and so not possible to give an answer.
Grams are mass. There's no calculation involved.
The molar mass of anhydrous sodium carbonate is 105,9888 g.
The mass of paper is usually given as grams per squaremetre. You still need to provide the width to calculate the mass, and from there to calculate the weight.
Molar mass of calcium carbonate/calcium valence = 50,04345
106 grams
The equation given shows that each formula mass of calcium carbonate produces one formula mass of CO2. The gram formula masses of calcium carbonate and carbon dioxide are 100.09 and 44.01 respectively. Therefore, to produce 4.4 grams of carbon dioxide, 4.4(100.09/44.01), or 10 grams of calcium carbonate, to the justified number of significant digits, are needed.
grams and to calculate use a pan balance
you take the atomic mass of the atom (or molecule) and you have the mass in grams
mass of CaCO3 = 246 grams
Given, molar mass, coefficient ratio, molar mass, answer
1400 grams
mass of CaF3 = 61.96g mass of Al2CO3 =61.104 g
