Answer:
c
Explanation:
all the atoms must be balanced.
There are two valence electrons.
Mass of block, m = 5.26 lb
1 lb = 453.592 g
5.26 lb = 2385.896 g
V = 14 in3
1 in = 2.5 cm
1 in3 = 15.625 cm3
14 in3 = 218.75 cm3
Density = mass/volume
= 2358.896 / 218.75
= 10.783 g/cm3
Answer:
the new volume is 1.49 L
Explanation:
stp is 0 degrees C and 1 atm.
you need to use the combined gas law formula and solve for v2
i converted the C to Kelvin
v2=p1(v1)(t2)/p2(t1)
v2=1atm(3.6L)(283.15K)/2.5atm(273.15K)
v2=1.49
