| The graph shows that at a temperature of +10 C in 1 cubic meter. m of air contains a maximum of 9.41 grams of steam. We calculate the relative humidity from the ratio of the actual amount of steam (according to the condition 6 grams) to the maximum possible:

6 / 9.41 = 0.638

Converting to percentages: 0.638 x 100% = 63.8%

Answer: the relative humidity of the air under these conditions is 63.8%.
