If te squre is inscribe in the cercle ten:The area of the circle is πR²
& the Area of te square is 2R², then the probability to land in the square :
2R²/πR²=2/π=0.6366 or 63.66%
Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
