hram777 [196]

Answer:

Amount of milk in grams = 95 gram

Explanation:

Given:

Volume of mix solution = 100 ml

Percent of powered milk = 5%

Find:

Amount of milk in grams

Computation:

Assume;

1 ml = 1 gram

Amount of milk = 100 - 100(5%)

Amount of milk = 100 - 5

Amount of milk = 95 ml

Amount of milk in grams = 95 gram

Compute the sugar content in an 8 oz sample of a soft drink. If the sugar content as per label on the product =10g per 100ml.​
Nataly_w [17]

Answer:

m_{sugar}=23.7g\ sugar

Explanation:

Hello,

In this case, we can first compute the volume of the sample in mL from the ounces:

8oz*\frac{29.5735mL}{1oz} =236.6mL

Thus, with the volume of the sample, we can compute the amount of sugar given the 10 g of sugar per 100 mL of soft drink as shown below:

m_{sugar}=236.6mL*\frac{10g\ sugar}{100mL}\\ \\m_{sugar}=23.7g\ sugar

Best regards.

I add 3.20 moles of Cu to an excess of AgNO3. How many miles of silver are formed?
nexus9112 [7]
<h3>Answer:</h3>

3.2 moles

<h3>Explanation:</h3>

The equation for the reaction between copper and sliver nitrate is given by;

Cu + AgNO₃ → Ag + CuNO₃

  • This is a single replacement reaction in which copper which is more reactive than silver displaces silver from its salt.

We are given;

  • Moles of copper, Cu as 3.2 moles

We are required to calculate the moles of silver metal formed.

We need to first determine the mole ratio of Cu to Ag

  • From the equation 1 mole reacts to form 1 mole of silver metal
  • Therefore, mole ratio of Cu to Ag is 1 : 1
  • Thus, moles of Cu = Moles of Ag

Hence,

The number of moles of Ag formed is 3.2 moles
