1. Al(C₂H₅)₂OCl₃

Al(C₂H₅)₂OCl₃ is made from 5 different elements. They are Al, C, H, O and Cl. Number of atoms in each element can be found as follows.

number of Al atoms = 1
number of C atoms = 2 x 2 = 4
number of H atoms = 5 x 2 = 10
number of O atoms = 1
number of Cl atoms = 3
<span>
Total number of atoms = 1 + 4 + 10 + 1 + 3 = 19

2. </span>BCl₃<span> 

BCl</span>₃ is a simple neutral molecule. It consists of 2 different elements as B and Cl. Total number of atoms is 4. Number of atoms can be calculated as follows.

number of B atoms = 1
number of Cl atoms = 3

Total number of atoms = 1 + 3 = 4<span>

3. </span>H₂O + H⁺

H₂O makes H₃O⁺ (hydronium ion) with H⁺ which is a positive ion. H₃O⁺ consists of two different elements as H and O. Number of atoms are as follows.

number of H atoms = 3
number of O atoms = 1

Total number of atoms = 3 + 1 = 4

A chemist adds of a M zinc nitrate solution to a reaction flask. Calculate the mass in grams of zinc nitrate the chemist has add
weqwewe [10]

corrected question: A chemist adds 135mL of a 0.21M zinc nitrate solution to a reaction flask. Calculate the mass in grams of zinc nitrate the chemist has added to the flask. Round your answer to significant digits.

Answer:

5.37g

Explanation:

0.21M means ; 0.21mol/dm³

1dm³=1L , so we can say 0.21mol/L

if 0.21mol of Zinc nitrate is contained in 1L of water

x   will be contained in 135mL of water

x= 0.21*135*10³/1

=0.02835moles

number of moles=  mass/ molar mass

mass= number of moles *molar mas

molar mass of Zn(NO₃)₂=189.36 g/mol

mass= 0.02835 *189.36

mass=5.37g

Calculate the relative atomic mass of M
aalyn [17]

Answer:

63.55

Explanation:

relative atomic mass=(mass of isotope1×relative abundance)+(mass of isotope 2×relative abundance)/100

r.a.m=(62.93×69.09)+(64.93×30.91)/100

=(4347.8337)+(2006.9863)/100

=6354.82/100

=63.55
