You are given a sample resembling silver. Which of the following properties could be used to help determine whether the sample i
defon

Answer:

the density of the sample - the melting point of the sample

Explanation:

Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.

For example,

Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.

Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.

What mass of K2CO3 is needed to prepare 200. mL of a solution having a potassium ion concentration of 0.150 M
I am Lyosha [343]

<u>Answer:</u>

2.07 grams

<u>Explanation:</u>

We know that the molecular mass of K_2CO_3 is 138.205 grams.

In order to find out how many grams we need to make 200 mL having a potassium ion concentration of 0.150, we need to find the number of moles first.

M = moles / liters

0.150 = x / 0.200

x = 0.03 moles

Since there are 2 potassium atoms in each molecule of K_2CO_3 so we will divide this number by half and multiply it by the molecular mass.

0.03/2 = 0.015 moles

Mass of K_2CO_3 needed = 0.015 × 138.205 = 2.07 grams
