How many grams of Carbon are in sample of 400 grams of Co2?​
RoseWind [281]

Answer:

Mass of carbon = 109.1 g

Explanation:

Given data:

Mass of carbondioxide = 400 g

Mass of carbon = ?

Solution:

Molar mass of carbon = 12 g/mol

Molar mass of CO₂ = 44 g/mol

Mass of carbon in 400g of  CO₂:

Mass of carbon = 12 g/mol/44 g/mol × 400 g

Mass of carbon = 109.1 g

If the mass of an object is 6 lbm, what is its weight, in lbf, at a location where g = 32.0 ft/s2?
Solnce55 [7]

Using formula:

w = m\times g   -(1)

where w is weight of object,

m is mass of the object, and

g is the acceleration of gravity.

mass, m = 6 lbm (given)

acceleration of gravity, g = 32.0 ft/s^{2} (given)

Now, substituting the values in equation (1):

w = 6 lbm \times 32 ft/s^{2} = 192 lbmft/s^{2}

Since, 1 lbf = 32.174 lbm ft/s^{2}

So, w = 192\times \frac{1}{32.174 lbf}

w = 5.976 lbf

Hence, the mass of an object is 5.976 lbf.
