Answer:
9.03 x 10²³atoms
Explanation:
Given parameters:
Number of moles of CO₂ = 1.5mol
Unknown:
Number of atoms = ?
Solution:
In a mole of a substance, we have the Avogadro's number of particles which is 6.02 x 10²³atoms.
Using this number, we can determine the amount of atoms in any substance.
If;
1 mole of CO₂ contains 6.02 x 10²³ atoms;
1.5mole of CO₂ will contain 1.5 x 6.02 x 10²³ atoms
= 9.03 x 10²³atoms
mass h
<h3>
</h3>
Explanation:
molar mass is equal to number of mass over moles we take 14.19 over17 molar mass of ammammonium equals 0.8347 incase of moles. 1H=1Nh3 ,so. n.H=0.8347 Mr=2 ,M.H=? Mr=m/n. 0.8347x2=1.669grams
1 mole of MgS = 24.3 + 32.1 = 56.4 g
35.1 g MgS x 1 mol / 56.4 g = 0.622 mol
M = 0.622 mol / 0.835 L = 0.745 mol/L
The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.
<h3>What is radioactivity?</h3>
Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.
The radioactive particles that are usually emitted include:
- alpha particles
- beta particles and
- neutrons
The neutron has a mass of 1.
When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.
