1. Convertir gramos de H_2 a moles:
\frac{10 \text{g } H_2}{2 \text{ g/mol}} = 5 \text{ mol } H_2
2. Usar la estequiometría de la reacción para encontrar moles de H_2O producidos:
5 \text{ mol } H_2 \times \frac{2 \text{ mol } H_2O}{2 \text{ mol } H_2} = 5 \text{ mol } H_2O
3. Convertir moles de H_2O a gramos:
5 \text{ mol } H_2O \times 18 \text{ g/mol } = 90 \text{ g } H_2O
4. Resultado final:
90 \text{ g } H_2O

Farm Grown, Inc., produces cases of perishable food products. Each case contains an assortment of vegetables and other farm products. Each case costs $5 and sells for $15. If there are any not sold by the end of the day, they are sold to a large food processing company for $3 a case. The probability that daily demand will be 100 cases is 0.30, the probability that daily demand will be 200 cases is 0.40, and the probability that daily demand will be 300 cases is 0.30. Farm Grown has a policy of always satisfying customer demands. If its own supply of cases is less than the demand, it buys the necessary vegetables from a competitor. The estimated cost of doing this is $16 per case. (a) Draw a decision table for this problem (b) What do you recommend?
The average weekly earnings in the leisure and hospitality industry group for a re‐ cent year was $273. A random sample of 40 workers showed weekly average ear‐ nings of $285 with the population standard deviation equal to 58. At the 0.05 level of significance can it be concluded that the mean differs from $273? Find a 95% con‐ fidence interval for the weekly earnings and show that it supports the results of the hypothesis test.
