Example:
Mass = ?
Density = 25 g/mL
Volume = 5 mL
therefore:
d = m / V
25 = m / 5
m = 25 x 5
m = 125 g
hope this helps!
Hard question !! Is this math .. if not then oh okay cause I’m bad at math but good at everything else so let me think about it !
Answer:
›› FeBr2 molecular weight. Molar mass of FeBr2 = 215.653 g/mol. This compound is also known as Iron(II) Bromide. Convert grams FeBr2 to moles or moles FeBr2 to grams. Molecular weight calculation: 55.845 + 79.904*2 ›› Percent composition by element
Explanation:
The condensed structural formula of the product of the reaction of 2,7-dimethyl-4-octene with hydrogen and metal catalyst.
Ch3 CH(CH3) CH2 CH2 CH2 CH2 CH(CH3) CH3
Equation is as follows
CH3 CH(CH3) CH2 C=C CH2 CH(CH3) CH3 + H2→
CH3 CH(CH3)CH2 CH2 CH2 CH2 CH(CH3) CH3
metal catalyst example is nickel and the name of structure formed is
2,7- dimethyl octane
Answer:
D
Explanation:
wavelength = speed of light/ frequency
= (3 x 10^8 m/s) / (3 x 10^12 Hz)
= 1 x 10^-4 m
