Answer:
0.01395mol Cr2O3
Explanation:
the molar mass of Cr2O3 is 151.9904 g/mol
2.12g Cr2O3 x 1 mol/151.9904g = 0.01395mol Cr2O3

Answer:
A) 60
Explanation:
Given data:
Distance traveled by car = 210 km
Time taken = 3.5 hour
Speed of car = ?
Solution:
Formula:
S = d/t
s = speed of car
d = distance
t = time
by putting values,
s = 210 km / 3.5 hour
s = 60 km/hour
