Common table salt is 39.3% sodium by mass. What mass of table salt provides the upper safe limit in the recommended daily requirement of sodium which is 2300mg?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is 303.15 or 303

can you list the answers so i can answer

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
