Explanation:
Ca + NaCl ----> CaCl2 + Na
A. DNA is copied.
- The cell duplicates its DNA in order to have a complete set in eac cell when it divides.
My view point is that i disagree and that the rules are completely different
1 mole contains = 6.02x10^23 atoms. 0.31mole contains = 0.31x6.02x10^23 = 1.8662x10^23.
Molar mass H₂SO₄ = 98.079 g/mol
1 mol -------- 98.079 g
? mole ------ 0.0960 g
moles = 0.0960 * 1 / 98.079
= 0.0960 / 98.079
= 9.788 x 10⁻⁴ moles
hope this helps!
