Answer:
4.5g/mL
Explanation:
Given parameters:
Mass of ball = 36g
Volume of the ball = 8mL
Unknown:
Density of the ball = ?
Solution:
Density is the mass per unit volume of a substance.
Density = 
So;
Density = 
= 4.5g/mL
Answer:
0.4515 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 10.0 mL
M₂ = 0.100 M
V₂ = 45.15 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 10.0mL = 0.100 M * 45.15 mL
M₁ = 0.4515 M
Hence, the concentration of the acetic acid = 0.4515 M
Answer:
0.036 g
Explanation:
<em>0.036 g of water should be produced.</em>
From the equation of reaction, 1 mole of HCl requires 1 mole of NaOH in order to produce 1 mole of H2O.
20 mL of 0.10 M HCl contains 20/1000 x 0.10 = 0.002 moles of HCl
46 grams of NaOH contains 46/40 = 1.15 moles of NaOH
<em>It thus means that the HCl is a limiting reagent in the reaction.</em>
From the equation:
1 mole HCl will produce 1 mole of H2O.
0.002 HCl with therefore produce 0.002 x 1/1 = 0.002 mole of H2O
<em>Mass of water produced = mole x molar mass</em>
0.002 x 18 = 0.036 g.
Hence, 0.036 g of water would be produced.
Nonene. Since it has c-c double bonds, we can be sure that its an alkene. To know its name, we can deduce from the number of carbon atoms ie 9.
