Nitrogen gas has a molar mass of about 28.0134 g/mol. Then we have a starting amount of
(42 g) / (28.0134 g/mol) ≈ 1.4993 mol
of N₂.
At standard temperature and pressure, one mole of an ideal gas occupies a volume of about 22.4 L. Then 42 g, or 1.4993 mol, of N₂ takes up
(1.4993 mol) × (22.4 L/mol) ≈ 33.6 L
I solved it and got 374.2N so i would put 375N
sorry i didn’t get any of the ones on there, i probably made a mistake.
Answer:
The speed of the block when it is 5.00 m from the top of the incline is 3.04 m/s
Explanation:
given information:
s = 7.80 m
v = 3.8 m/s
if s = 5 m, v?
first we have to find the acceleration of the block using the following equation:
v² = v₀² + 2as, v₀² = 0 thus
3.8² = 2 a 7.8
a = 0.93
so, if s = 5m the final speed is
v² = 2 (0.93) (5)
= 9.26
v = √9.26
= 3.04 m/s
