A particular brand of gasoline has a density of 0.737 g/ml at 25 ∘c. how many grams of this gasoline would fill a 13.0 gal tank

Usimov [2.4K]

Density of gasoline is 0.737 g/mL and volume of tank is 13.0 gal.

Since, 1 US gal=3.78 L

Volume of tank in L will be:

$V=13.0 gal(\frac{3.78 L}{1 gal})=49.14 L$

Also, 1 L=1000 mL

Thus,

$V=49.14 L(\frac{1000 mL}{1 L})=49140 mL$

Mass of gasoline can be calculated as follows:

m=d×V

Here, d is density and V is volume thus,

$m=0.737 g/mL\times 49140 mL=3.62\times 10^{4}g$

Therefore, mass of gasoline will be $3.62\times 10^{4}g$ .

Hello

Answer:

The ratio of the number of atoms of gold and silver in the ornament is 197 : 1080.

Explanation:

Let the mass of silver ornament be x.

Mass of gold polished on an ornament = 1% of x= 0.1 x

Moles of silver = $\frac{x}{108 g/mol}$

Number of atoms = $Moles\times N_A$

Where : $N_A$ = Avogadro number

Moles of gold = $\frac{0.1x}{197 g/mol}$

Silver atoms = $\frac{x}{108 g/mol}\times N_A$

Gold atoms = $\frac{0.1x}{197 g/mol}\times N_A$

The ratio of the number of atoms of gold and silver in the ornament:

$=\frac{\frac{0.1x}{197 g/mol}\times N_A}{\frac{x}{108 g/mol}\times N_A}$

= 197 : 1080

Number 51 is 0.00150 ml to l

xenn [34]

Answer:

The answer to your question is

51.- 1.59 x 10⁻⁶

53.- NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl

Explanation:

51.- Convert 0.00159 ml to liters

Use a rule of three

1000 ml -------------- 1 l

0.00159 ml --------- x

x = (0.00159 x 1) / 1000

x = 0.00000159 l = 1.59 x 10⁻⁶ l

53.- Sodium hydrogen carbonate (NaHCO₃) reacts with hydrochloric acid to produce salt, water and carbon dioxide.

Sodium hydrogen carbonate = NaHCO₃

Hydrochloric acid = HCl

Reaction

NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl

water = H₂O

carbon dioxide = CO₂

salt = NaCl
