The atomic mass of Aluminum is around 27 amu. There are two aluminum atoms, so it takes 54 amu. The gram-formula states that 1 mole of this compound has 342 grams. By definition, this means that the total amu of this compound is 342. Therefore, we divide 54 by 342 to get around 15.8 %.
The control group is the type of tomato the plants are.
The independent variable is the type of music played.
The dependent variable is Plant A and B's growth.
His conclusion should be that music does not affect the growth of tomatoes.
He should make sure both plants were getting the same amount of water, soil, light, seed, and fertilizer so that can't affect the tomatoes in any way.
There are 6.022*10^23 molecules in 1 mole of carbon
So how many will moles will be 7.87*20^7?
Let the required number of moles be ‘x’.
1 mole ———6.022*10^23
x moles———7.87*10^7
(Cross multiplication)
x=7.87*10^7/6.022*10^23
Therefore x=1.3*10^-16
Same here no one answers my questionssssss
