Abeaker with saltwater was left uncovered and all water evaporated. if there are 0.505 g of nacl left in a beaker that originally contained 75.0 ml of saltwater, what must have been the concentration of the original solution?

Which compound contains both ionic and covalent bonds? a) hbr b)cbr4 c)nabr d) naoh

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
