Answer:
if its 5X 10^3 mm=5m and if its 5X 10^-3 mm=5X 10^-6m
Explanation:
we know,
1m= 1000mm
as given 5X 10^3 mm we have to convert to meter
now 5X 10^3 mm= 5X 10^3/1000=5m
but if its 5X 10^-3 mm= 5X 10^-3/1000= 5X 10^-6m

Answer: 2 C2H4 + 6 O2 => 4 CO2 + 4 H2O
Explanation:The coefficient are as follows: 2: 6: 4: 4
Each atom on the reactant and product side are equal.
Reactant Product
C 2x2 = 4 4x1 = 4
H 2x4 = 8 4x2 = 8
O 6x2 = 12 (4x2) + 4 = 12
Answer:
B) 125 mL
Explanation:
M1V1=M2V2
(0.120M)(x)=(150.0 mL)(0.100M)
x= 125 mL

Answer:
The answer to your question is: 0.05 M
Explanation:
I'm not sure about the units umol, I think is units mol.
Data
MgF2 = 0.0191 mol
Volume = 400 ml
Molarity = moles / volume
Molarity = 0.0191 / 0.4 l
Molarity = 0.048 ≈ 0.05 M
