Answer:

15.38 g is the mass for M in the 329 g of sample

Explanation:

Mineral's formula: MS

Our sample weighs 44.9 g

Mass of M: 2.1 g

Our new sample weighs 329 g

We may solve this by a rule of three:

44.9 g of sample contain 2.1 g of M

329 g of sample will contain (329 . 2.1) / 44.9 = 15.38 g

Answer:

In a 329 grams mineral, we have 15.4 grams of metal M

Explanation:

Step 1: Data given

Mass of the sample = 44.9 grams

The mineral contains: 2.1 grams of M

Step 2: Calculate mass % of M

mass % of M = (mass M / total mass sample) * 100 %

mass % of M = (2.1 grams / 44.9 grams) *100 %

mass % of M = 4.677 %

Step 3: Calculate the mass of M in a 329 grams

Mass % = (4.677 grams / 100 % ) * 329 grams

Mass % = 0.04677 * 329 grams

Mass % =  15.4 grams

In a 329 grams mineral, we have 15.4 grams of metal M

A student measures the volume of a solution to be 0.01370 l. How many significant digits are in this measurement?
Mkey [24]

A student measures the volume of a solution to be 0.01370 have 5 significant digits in this measurement.

<h3>What are significant digits?</h3>

The significant digits are the minimum number from zero to nine for reporting any measurement where the digits are uncertain.

The significant digits starting from zero are not significant digits, decimal is not a significant digit, and ending zero after the decimal are significant digits.

Therefore, the student measures the volume of a solution to be 0.01370 5 significant digits are in this measurement.
