Why is it important to check for violations of assumptions when hypothesis testing?

What’s the percent by mass of carbon in c10h14n2

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
