Answer:
168.812 g/mol
Explanation:
atomic mass. of Be= 9.012
atomic mass of Br= 79.90
because there is a 2 after Br you double the atomic mass
79.90(2)= 159.8
To find the molar mass add the atomic masses of each element
9.012+159.8=168.812
Mass (g) / Volume (cm^3) = Density (g/cm^3)
60.4g/ 11.3 cm^3 = 5.35 g/cm^3
d= 5.35 g/cm^3
Answer: an organic base, a phosphate group, and a sugar
Explanation:
A nucleotide is made up of 3 parts. We know a nucleotide is not made up of water so we are left with 2 choices. Nucleotides are made up of phosphate group, 5-carbon sugar, and nitrogenous base. The nitrogeneous base is typically adenine. The answer choice that matches this the closest is an organic base, a phosphate group, and a sugar.
The organic base is the nitrogeneous base and the sugar is the 5-carbon sugar.
Answer:
In this case, ethanol's molecular mass is 46 g/mol. This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably. The same is true of a mole. A mole of anything is 6.022 x 1023 of that item
