Calculate the stroke volume if the end diastolic volume (edv) is 135 ml/beat and the end systolic volume (esv) is 60 ml/beat.

Answer;

= 75 mL

Explanation;

The SV is calculated by subtracting the ESV from the EDV. You are comparing the volume of the ventricle at its fullest to its emptiest.

Therefore;

Since diastolic volume is 135 mL/beat and systolic volume is 60 mL/beat

Thus; stroke volume = 135 mL/beat - 65 mL/beat

                                   = 75 mL/beat

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

they are both synthetic elements
