Answer:30.27 g HNO3
Step by step solution:
45 g Cu x 1 mol Cu / 63.54 g Cu
= 0.1802 mol Cu
0.1802 mol Cu x 8 mol HNO3/3 mol Cu =0.4805 mol HNO3
Molar Mass HNO3
= 1.0 + 14.0 +3×16.0
= 63.0 g/mol
0.4805 moles HNO3 x 63.0 g HNO3/1 mol HNO3
= 30.27 g HNO3
D. Sweat evaporating from the skin cools the body because so much heat is removed while it evaporates
Answer:
P2= 45.50 atm
Explanation:
If the amount of gas in the tanks remains same we use the equation P1T1=P2T2
40 x 281.15 = P2 x 247.15
P2= 45.50 atm
Something moving. Change in temperature.
