Use the periodic table to calculate the molar mass of each compound below. Give your answer to the correct number of significant
agasfer [191]
From the periodic table you get the atomic masses of each element.

These are the values that I have in my periodic table (use those numbers of your periodic table if your teache gave you a specific one)

Na: 23 g/mol
O: 16 g/mol
H: 1 g/mol
C: 12 g/mol
Ca: 40 g/mol
S: 32 g/mol
Mg: 24 g/mol
P: 31 g/mol

Now I will do some examples and you do the others:

1) NaOH: 1 atom of Na * 23 g/mol + 1 atom of O * 16 g/mol + 1 atom of H * 1 g/mol

=> 1*23g/mol + 1*16g/mol + 1*1g/mol = 40 g/mol

2) H2O

=> 2 atoms of H * 1 g/mol + 1 atom of O * 16 g/mol = 2*1g/mol + 1*16g/mol = 18 g/mol

3) Glucose: C6H12O6

6*12 g/mol + 12 * 1g/mol + 6*16 g/mol = 72g/mol + 12g/mol + 96 g/mol = 180 g/mol

4) CaSO4:

1*40 g/mol + 1*32g/mol + 4*16g/mol = 136 g/mol

Now you only have to do the last one by your own.

What are the major organic products are formed when the following compounds react with methylmagnesium bromide (CH3MgBr), follow
Sliva [168]

Answer:

Major organic products are- (a) propan-1-ol and (b) 2-methylpropan-2-ol

Explanation:

methyl magnesium bromide gives nucleophilic addition reaction with carbonyl group. Because methyl magnesium bromide is a strong nucleophile and carbonyl group is a strong electrophilic center.

Propanal contains an aldehyde group and propanone contains a ketone group. hence they both give nucleophilic addition with methyl magnesium bromide.

Dilute acid is added to protonate the alkoxide produced during nucleophilic addition.

Reactions are shown below.
