Mass because an intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. Examples of extensive properties include: volume, mass, size, weight, and length.
The density of liquid water is 1 kg/L.
Mass of water = (1 kg/L)(2.5 L)(1000 g/1 kg) = 2500 g water
The molar mass of water is 18 g/mol.
Moles of water = 2500 g / 18 g/mol = 138.889 mol water
According to Avogadro's number, in one mole of any substance, there are 6.022×10²³ atoms.
Atoms of water = 138.889 mol * 6.022×10²³ atoms/mol = 8.364×10²⁵ atoms of water
In every atom of water, there are 10 protons: 8 from one oxygen atom, and 1 each from the two hydrogen atoms.
Protons of water = 8.364×10²⁵ atoms * 10 protons/atom
<em>Protons of water = 8.364×10²⁶ </em>
the answer to your question is
ρ≅13.0⋅g⋅mL−1 = 13.0⋅g⋅cm−3Explanation:Density=Mass Per unit Volume = 75.0⋅g(36.5−31.4)⋅mL =??g⋅mL−1Note that 1⋅mL = 1⋅cm−3; these are equivalent units of volume; i.e. 1⋅cm3 = 1×(10−2⋅m)3=1×10−6⋅m3=10−3⋅L=1⋅mL.
Answer:
523.66g or 524g for proper sig figs
Explanation:
First you have to get the molar mass of MgCl2 which is 95.211g/mol. You can calculate this through added the atomic mass of one magesium atom and 2 chloride atoms. You then multiply the 5.50mol by the 95.211g/mol and that cancels out the unit of moles leaving only grams.
Answer:
The Earth's magnetic field intensity is roughly between 25,000 - 65,000 north magnetic pole is 86.50°N and 164.04°E and the south magnetic pole is 64.07°S and 135.88°E
