Answer:
The repeating pattern of a mineral's particles form a solid called a <u>crystal</u>.
Explanation:
Equation: M1V1 = M2V2
Where M = concentration & V = volume
Step 1: Write down what is given and what you are trying to find
Given: M1 = 1.25M, V1 = 46mL, and V2 = 250mL
Find: M2
Step 2: Plug in the values into the equation
M1V1 = M2V2
(1.25M)(46mL) = (M2)(250mL)
Step 3: Isolate the variable (Divide both sides by 250mL so M2 is by itself)
(1.25M)(46mL) / (250mL) = M2
Answer: M2 = 0.23M
A)
The additional mass is that of Oxygen
4.666 - 3.555
= 1.111 g
B)
The percentage mass of oxygen can be obtained by:
[(mass of Oxygen)/ (Total mass of product)] * 100
= (1.111 / 4.666) * 100
= 23.81%
