How many liters of cane juice is needed to supply 5g sucrose if cane juice contains 12% sucrose
pickupchik [31]

Given parameters:

Mass of sucrose  = 5g

Density of sucrose  = 1.12g/mL

Percentage of sucrose per liter of cane juice  = 12%

Unknown:

Volume of cane juice needed = ?

We need to establish the volume - density relationship. Density is the mass of a substance per unit volume.

Mathematically;

                Density  = \frac{mass}{volume}

Now solve for the volume of sucrose;

                  1.12g/mL = \frac{5}{Volume}

       Volume  = \frac{5}{1.12}    =  4.46mL   = 4.46 x 10⁻³L since 1000mL  = 1L

Since 12% of 1 liter of cane juice is sucrose;

                    12% of  x  liter of cane juice  = 4.46 x 10⁻³L

                   Volume of cane juice  = 4.46 x 10⁻³ x \frac{100}{12}   = 0.037L

Volume of cane juice is  0.037L

A housewife purchases a 3.0 lb. roast, what is its weight in grams
Afina-wow [57]

The weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.

<h3>What is weight?</h3>

The weight of an object is the force acting on the object due to gravity.

The weight of an object varies from place to place across the globe due to difference in acceleration due to gravity.

<h3>Weight of the roast in grams</h3>

1 lb ------------> 453.592 grams

3 lb ------------> ?

= (3 x 453.592)

= 1,360.78 grams

Thus, the weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.
