You're answer should be 0.25
.025 is the thousandths place.
brainliest? :p
Theoretical probability is the number of desired outcomes (heads) divided by the total number of outcomes (heads or tails). The actual outcome does not affect the theoretical probability. Mark is correct.
Answer:
−7×(−6)×5= 210
Step-by-step explanation:
80 divided by 8 = 10 and 10+2 = 12 sooo the number is 80. :)
<span>13.2 gallons=49.9 liters
the gas is the octan C8H18
the combustion of Octan equation is
C8H18 + 25/2 O2-------------------> 8CO2 + 9 H2O
1mole 8 moles
n(C8H18)=a n(CO2)=b
so
1 mole/a = 8moles /b
and b= 8molesx a
we must find the value of a, molar volume of a gas is v= 22.4l/mol=V/a, so a=V/v= 49.9/22.4= 2.23 moles
and b=8 x a=8x 2.23=17.85 moles
M(CO2)=m(CO2)/n(CO2)====> m=n x M=17.85 * (12+2x16)= 785.4 g
m(CO2)=785.4g = 1.57 pound</span>
