How many gram-moles of formic acid, ch2o2, are in 225 g of the compound? numbe g-mol ch,0, how many pound-moles of formic acid are in 225 g of the compound? number ib-moles ch, o,

Explanation:

(a)     Mass given = 225 g

        Molecular mass of = = 12 + 2 + 32 = 46 g/mol

As, it is known that number of moles is equal to the mass divided by molar mass.

Mathematically,        No. of moles =

Hence, calculate the number of moles of formic acid as follows.

                     No. of moles =

                                           = 4.89 mol or g mol

Hence, in 225 g of the compound there are 4.89 mol or g mol.

(b)   It is known that 1 g = 0.0022 pound

So, pounds present in 4.89 g will be calculated as follows.

                       4.89 \times 0.0022 pound

                     = 0.0107 pound mole

Hence, in 225 g of the compound there are  0.0107 pound mole.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
