Ammonium phosphate fertilizer is prepared by the following reaction: 3NH3(g) + H3PO4(aq)  (NH4)3PO4(s) (a)  Calculate the molar mass of ammonia, phosphoric acid and ammonium phosphate. (b)  How many moles of ammonium phosphate are present in a 5.00-pounds bag of (NH4)3PO4?Ammonium phosphate fertilizer is prepared by the following reaction: 3NH3(g) + H3PO4(aq) 

Calculate the molar mass of ammonium phosphate, (NH4)3PO4.149.0 g/mol113.0 g/mol242.0 g/mol121.0 g/mol The Correct Answer and Explanation is : The molar mass of ammonium phosphate, ((NH_4)_3PO_4), can be calculated by adding the molar masses of all the atoms in the formula. Therefore, the molar mass of ammonium phosphate ((NH_4)_3PO_4) is approximately 149.0 g/mol, and the

Newell and Jeff are the two barbers in a barber shop they own and operate. They provide two chairs for customers who are waiting to begin a haircut, so the number of customers in the shop varies between 0 and 4. For n = 0, 1, 2, 3, 4, the probability Pn that exactly n

An alternating voltage is given by V=230sin314t.Calculate i)frequency,ii)maximum value,iii)average value,iv)RMS value.(N/D-2016) The Correct Answer and Explanation is : Let’s break down the given alternating voltage equation: [V = 230 \sin(314t)] i) Frequency The general form of the alternating voltage equation is: [V = V_{\text{max}} \sin(\omega t)] Where: From the equation, the angular frequency ( \omega
