Answer:
40
Step-by-step explanation:
Using the method of prime factors
8 = 2 × 2 × 2 = 2³
2 = 2
5 = 5
Then LCM = 2³ × 5 = 8 × 5 = 40

c is the correct answer..........
Answer:
e = 1.04
Step-by-step explanation:
To find e, we apply the sine rule
e/sineE = f/sineF
e/sine55 = 1.2/sine109
e/0.8192 = 1.2/0.9455
0.9455e = 1.2 x 0.8192
e = 0.9830/0.9455
e = 1.0397
to nearest tenth = 1.04inch
The number of mole of pure 11C (carbon-11) initially present is 0.2727 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation
Mole = mass / molar mass
With the above formula, we can obtain the number of mole of pure 11C. Detail below:
<h3>How to determine the mole of 11C</h3>
From the question given, the following data were obtained:
- Molar mass of 11C = 11 g/mol
- Mass of 11C = 3 g
- Mole of 11C =?
Mole = mass / molar mass
Mole = 3 / 11
Mole = 0.2727 mole
Therefore, the number of mole of pure 11C initially present is 0.2727 mole
