Answer:
0.779 cube centimetres
Explanation:
density = mass divided by volume
rearrange the equation to solve for volume: 
plug in the corresponding values:
volume = 6.130 g / 7.87 (gcm^3)
the gs cancel, the answer will be 0.7789
we will round to three sig figs, since that's the lowest amount of figures in the given values: ~0.779 cm^3
Answer:
2.52atm for sure
Explanation:
We know that:
P1= 2.80atm
T1= 400k
T2= 360k
And we want to find P2= ?
We have an equation: P1/T1 = P2/T2
Multiple both side by T2 to remove it
P2 = 2.52
5.53*(6.023*10^23)= 33.30*10^27
