Answer:
The answer is the first option 0.37 moles
Explanation:
the ideal gas law is PV = nRT, so in the terms of n,
n = PV/RT (divide both sides by RT to let n stand alone)
given: P = 700 kpa, V = 2L, T = 450 K , R = 8.31
n = (700 * 2) / (8.31 * 450)
= 1400/3739.5
= 0.34
<span>SnSO4 • 7H2O
This formula has 2 part
1) </span>SnSO4 - <span>tin (II) sulfate
2) 7H2O - </span><span>heptahydrate (that means 7 molecules of water).
So full name is </span><span> tin (II) sulfate heptahydrate.</span>
