Imagine you have two beakers of 75 g each. You pour 50 g of water in one beaker and 100 g of vinegar in the second beaker. Placing both containers on the scale you measure 300 g. You pour the water in with the vinegar and measure the mass of the beaker of liquid. Based on the information above and the image below, what does your scale read? 300 g
150 g
375 g
225 g

your answer would be a. 12.5 kg

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

i don,t know so just answer mine
