Answer:

Mass percent of food dyes  = 0.0616%

Explanation:

Given data:

Mass of candy = 47.9 g

Calories = 240

Mass of fat = 10 g

Mass of carbohydrate = 34 g

Mass of protein = 2 g

Mass of food dyes = 29.5 mg

Mass percent of food dyes = ?

Solution:

First of all we will convert the mg into g.

Mass of food dyes = 29.5 mg × 1g /1000 mg = 0.0295 g

Mass percent of food dyes  = mass of food dyes / total mass× 100

Now we will put the values.

Mass percent of food dyes  = 0.0295 g / 47.9 g × 100

Mass percent of food dyes  =  0.000616 × 100

Mass percent of food dyes  = 0.0616%

DanielleElmas [232]
1) Calculate the number of moles of Cu SO4 . 5H20 by dividing the specified mass by the molar mass.

2) The ratio of production given by the equation is 1 mol of Cu SO4 . 5 H2O to 1 mol of Cu SO4=> 1:1, meaning that the number of moles of Cu SO4 produced is the same number of moles of Cu SO4.5H20 heated.

3) Finally mutiply the number of moles of Cu SO4 by its molar mass and there you have the mass of Cu SO4 produced.

What law states that the physical and chemical properties of the elements are periodic within the sequence of their atomic numbe
Soloha48 [4]

Answer:

Periodic Law.

Explanation:

The Periodic Law states that the physical and chemical properties of the elements repeat in a systematic and predictable way when the elements are arranged in order of increasing atomic number.

Many of the properties are repeated at intervals.

When the elements are arranged correctly, the trends in element properties become apparent and can be used to make predictions about unknown or unfamiliar elements, simply based on their placement on the table.

what is the volume in liters of 76 grams of fluorine (f2) at a temperature of 0 celcius and 101.3 kilopascals?
AlladinOne [14]

Answer:

V = 44.83 L

Explanation:

Given data:

Mass of fluorine = 76 g

Temperature = 0°C (0°C + 273 = 273 K)

Pressure = 101.3 Kpa ( 101.3 / 101 = 1 atm)

Volume of fluorine = ?

Solution:

Number of moles of F = Mass/ molar mass

Number of moles = 76 g/ 38 g/mol

Number of moles = 2 mol

Volume of fluorine:

PV = nRT

V = nRT/ P

V = 2 mol × 0.0821 atm. L/ mol. k × 273 k / 1 atm

V = 44.83 L. atm / 1 atm

V = 44.83 L

How many grams of LiOH are needed to make 25 mL of a 0.125 M solution?
MaRussiya [10]

Answer:

0.0734 grams LiOH

Explanation:

The molarity formula looks like this:

Molarity (M) = moles / volume (L)

You are given the molarity and volume (in mL). Therefore, you can plug these values into the equation and solve for moles (after you convert from mL to L).

25 mL / 1,000 = 0.025 L

0.125 M = moles / 0.025 L

(0.125 M) x (0.025 L) = moles

0.003125 = moles

After using the molarity formula, we know that 0.003125 moles LiOH are needed to satisfy these conditions. Now, we can convert this to grams using the molar mass of LiOH. This can be determined using the values from the periodic table. Remember to write your conversion in a way that allows for the units to cancel out.

Molar Mass (LiOH) = 6.941 g/mol + 16.00 g/mol + 1.008 g/mol

Molar Mass (LiOH) = 23.499 g/mol

0.003125 moles           23.499 g
------------------------   x   -------------------  =  0.0734 grams LiOH
                                        1 mole
