What is the molar mass of c3h8? a) 44.0 g b)11.0 g c)36.0 g d)6.02 × 1023 g

(A) 44.0 g/mol

Explanation:

Molar mass of a compound is the sum total of all the individual masses of the constituent elements present in the compound.

Molar mass of C3H8 =

C = 12.0 g/mol

H = 1.00 g/mol

Molar mass of C3H8 = (12*3) + (1*8) = 36 + 8 = 44 g/mol.

Molar mass of C3H8 = 44g/mol

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
