Answer:
Solution given:
Area of a given polygon [parallelogram]=
base*height=5*3=15cm²
Answer:
4
Step-by-step explanation:
The mean of 2x and 12 is (2x+12)/2, so we get the equation:
(2x+12)/2 = 10 =>
x+6=10
x = 10-6 = 4
* Your question states four numbers, but you write only two... the answer could be wrong because of that.
To calculate for mass, simply multiply molar weight (MW)
and number of mols. The molar weight (MW) is in units of mg / mmol. Therefore
the mass is:
mass = (158 mg / mmol) (0.25 mmol)
mass = 39.5 mg
Answer:
39.5
