The best way to determine the number of atoms of arsenic in the sample will be to multiply 2.3 by Avagadro's number.
This is because Avagadro's number is the number of particles one mole of any substance has, and its value is 6.02 x 10²³
If the number of moles of a substance are known, then multiplying by Avagadro's number will give the number of particles. In this case, this is 1.38 x 10²⁴.
The answer is (3) the same chemical properties. The two samples are under same condition so they have same density. The gram-formula mass is the property of the matter itself. So it will not change. The volume will change when mass changes.
It is used in such good quality papers that need high opacity, higher brightness and whiteness such as offset papers and bible papers. ... But only rutile and anatase are used in paper mill industries. Both are tetragonal crystalline system. Rutile has higher refractive index than anatase.
