Answer:
m Br = 439.472 g
Explanation:
mass Br = ?
∴ mol Br = 5.50 mol
∴ molar mass Br 79.904 g/mol
mass = (mol)*(g/mol)
⇒ m Br = (5.50 mol)*(79.904 g/mol)
⇒ m Br = 439.472 g
Answer:
imma go with the answer B
M1 * v1 = m2 * v2
<span>2.50 * v1 = 1 * 75
</span>2.50 * v1 = 75
2.50 * v1 /75= 75/75
<span>v1= 30 ml
The Answer is 30 ml</span>
Option one ( which is Aluminium Carbonate ) is the answer
Answer:
