Agas at 20.0°c is increased to 40.0°c, will its volume: if the original volume is 1.00 l, what would the new volume be

2.0 l

Explanation:

When for 20 °C volume is 1 l then for 40°C is going to be 2 l

201

40x

x=(40*1):20

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

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.
