The mass of chlorine that react with 9.00 g of Al to form AlCl3 is 35.465 grams
Explanation
write the equation for reaction
that is
2 Al + 3 Cl2 = 2 Al CL3
find the moles of Al reacted
moles = mass/molar mass
9 g/ 27 g/mol = 0.333 moles of Al
by use of mole ratio between Al to Cl2 which is 2:3 find the moles of Cl2
mole of cl2 = 0.333 x3/2 = 0.4995 moles
mass of Cl2 is therefore = moles x molar mass
= 0.4995 x71 = 35.465 moles
Answer:
= 3.01×
molecules.
Explanation:
1 mole of
- 98g
? moles of
- 49g
= 49 ÷ 98 = 0.5 moles of O2 in 49g.
But 1 mole of any substance = 6.023 ×
molecules
∴ 0.5 moles = 0.5 × 6.023 ×
molecules
= 3.01×
molecules.
