How many moles are there in 4.00 g of ethanol, ch 3ch 2oh?

Explanation:

Number of moles present in a substance is equal to the mass divided by molar mass.

Mathematically,      No. of moles =

As it is given that mass is 4.00 g and molar mass of is 46.07 g/mol.

Hence, calculate the number of moles of as follows.

                 No. of moles =

                                       =

                                       = 0.086 mol

Thus, we can conclude that number of moles of present in 4.00 g is 0.086 mol.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
