crab-eating frog

hi can i pls ask how do i solve question like this? The crab-eating frog uses two mechanisms to maintain its cells in osmotic balance with its environment. First, it allows the Na+ and Cl- concentrations in its cells to increase slowly as the ions diffuse down their concentration gradients. Second, like many elasmobranchs (sharks), it retains the waste product urea in its cells. The addition of both NaCl and urea increases the osmolarity of the cytosol to a level nearly equal to that of the surrounding environment. Assuming the volume of water in a typical frog is 100 mL, calculate how many grams of NaCl (FW 58.44 g/mol) the frog must take up to make tissues isotonic with seawater.
