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.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
