Popis:	We report the properties of molecular gas in a sample of six host galaxies of fast radio bursts (FRBs) obtained from CO observations with the Atacama Large Millimeter/submillimeter Array (FRBs 20180924B, 20190102C, and 20190711A) and results of one non-detection in a dwarf galaxy (FRB20121102A) and two events detected in M81 (FRB20200120E) and the Milky Way (FRB20200428A). The CO observations resulted in the detection of CO(3-2) emission in the FRB20180924B host and non-detections of CO(3-2) and CO(2-1) emission in the hosts of FRB20190102C and FRB20190711A, respectively. The derived molecular gas mass and 3$σ$ upper limit is $(2.4 \pm 0.2) \times 10^9$ $M_{\odot}$, $ Accepted for publication in ApJ Letters, 8 pages, 3 figures, 2 tables
