Question

how, many grams of phosphorous are contained in 3.07 x 1027 atoms of phosphorous? Enter your answer with the correct number of significant figures and in standard (not scientific) notation

Expert Solution

Step 1

The concept of mole is a conducive way to express the amount of particles.

This is a measurement unit in which $6.022 \times 10^{23} atoms of any substance weighs eqauls to its molar mass .$

Significant digits are general scientific notations which are used in science to assort the accuracy.

Given data;

$\begin{array}{rcl} No . of atoms of Phosphorus & = & 3.07 \times 10^{27} \\ Mass of 3.07 \times 10^{27} atoms of phopshorus & = & to be calculated . \end{array}$

Also,

$Mass of Phosphorus = 31 g / mol$
