creativ13 [48]2 years ago
3 0

Answer:

3.01×10²³ atoms of calcium

Explanation:

number of moles = number of atoms/Avogadro's constant

n = N/NA

N = n×NA = 0.500 mol×6.02×10²³ mol^-1

N = 3.01×10²³ atoms of calcium

Help!!

I believe this a PV = nRT question whereas

you re write the formula and solve for volume

V = nRT/ P

then you input the values

P= pressure constant

V= x

n = moles = 0.2540

R = gas constant should be 8.314J mol

T = C degrees + 273.15 = K

solve for voume

make sure all units match

and use sig figs!!!!
