Answer:
moles HCl = 101.2 g /36.461 g/mol=2.78
[H+]= 2.78 mol/ 150 L =0.0185
pH = - log 0.0185=1.73
1.73 is the answer
Answer:... I'm sorry.. I think you're missing something
Explanation:
Answer:
3.47 mol MnSO4
Explanation:
54.94 + 32.07 + (16 × 4) = 151.01g/mol MnSO4
542.32g / 151.01g/mol = 3.47 mol MnSO4
Answer:
57.6ml
Explanation:
Using dilution formula
C1V1 = C2V2
C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml
2.903 × V1 = 0.3344 × 500
V1 =( 0.3344 × 500)/ 2.903
= 57.5956
≈ 57.6ml
Lava is defined as a molten rock that is<span> from a volcano or from a fissure in the surface of the earth.

The lava that is very near the heat source is in a liquid state because it melted in the extreme heat. The farther away it moves from the heat source, the cooler it becomes until such time that it solidifies into rocks.
