Molar mass of iron is 56g.

Given mass of iron= 112g

No. of moles = Given mass/Molar Mass

=> 112g/56g= 2 moles

1112/32 moles for every mole of sulfur there are 32g

The recently named element copernicuim has the number 112.

n= 6,0/112 n= 0.05 mol

The atomic number of 112 starts with the atomic number 107. This is studied by scientist.

97.44 is 112% of 87

112 is an integer and so there is no sensible way of writing it as a mixed number.

It is: 7 because 7*112 = 784 which is a square number

112 / 0.14 = 800 Therefore, 112 is 14 percent of 800.

112 over 3 as a mixed number = 371/3

112/56.1056=1.996 so 2.0mole 2 moles/2 liters = 1 M

The formula for Ethylene_ C2H4 STEP 1 Calculate the RMM (Relative molecular mass) of C2H4 C-carbon= 12; H-hydrogen= 1 (check your periodic table people!!!) C*2 + H*4 = 12*2 + 1*4 = 24 + 2 =28 amu/g So... one mole of ethylene has a mass of 28 grams. Number of Moles= Mass / mass of 1 mole ("/" to divide) The mass given is 122g 122g/28g = 4.36 moles Approx 4.4 moles

112 = European Emergency Number

Not to get a whole number; 112/12 = 9.333.

481.6 is 430 percent of 112.

The number, 112 , is an integer. Therefore, writing it as a fraction would be of no value.

Both 47 and 61 are prime numbers. 112 is a composite number.

1 mole of an ideal gas occupies 22.4 liters at STP. So 112 liters would be occupied by 5 moles of an ideal gas.

112, 224, 336, 448 +112 . . .

it is a composite number

5 times 22.4 Litres = 112 L

That will depend on the temperature and pressure. At STP, you will have 5x22.4 = 112 liters

Fe=Iron (112 grams) O=Oxygen (48 grams) This is actually Iron Oxide, or Rust!

Atomic Number = 112

112 is an integer and not a fraction. However, it can be expressed in rational form as 112/1.

It actually is not a mixed number, 7 goes into 112 16 times, so the answer is 16.
